I thought you wanted it for something to happen in your book and it would never get around to happening if it took that many days!

My follow up question is this: Is this number the number of possible combinations for *all* the students? If so, how often would one particular grouping of four meet during those 10,626 times?<br /><br />Challenge problem: I have a follow up question that may turn some of the information into a red herring. If you are a girl and one of the other girls in the class was your best friend, how often could you expect to eat a meal with her?<br /><br />Would it help to assign the girl and her friend names? Girl X and Girl Y -- keeping it mathy.Author Amokhttps://www.blogger.com/profile/13636391982938592789noreply@blogger.comtag:blogger.com,1999:blog-8303906221917588052.post-58504282069476861652015-09-06T13:03:16.548-04:002015-09-06T13:03:16.548-04:0010,626 and 4,356 are correct.

It's a basic Bayesian combination.

There are 66 pair possibilities with just the boys and/or the girls. Combining them (as twosomes) would create 2,145 days of different foursomes. I'll keep checking, but have to go out.

I believe that you are looking at 10626 different 'groups' before you can sit with all the students in all possible groups. (I got that number off a lotto website.

(There are 10,626 possible foursomes, divided by six is 1,771.) For the challenge question, he thinks it's only 726 days. (There are 4,356 possible foursomes.)Tabathahttps://www.blogger.com/profile/14367572663591077922noreply@blogger.com
